Capturing GPS data
There is a road that has recently been constructed. It is up to you to capture the new road using a GPS receiver. With your GPS activated, you will walk the length of the new road segment and capture vertices for the length of the new road. This task is being done in Elmore, Australia but you can easily perform the same steps for a street or road in your local area. If you happen to be in Elmore than you can perform the exercise as is!
- Find the area where we are going to add the new road. It is located at the end of Strawthorn, west of the Vineyard we located in the previous exercise.
- Activate your GPS receiver if you have not already done so.
Refer to section, ‘Connecting your GPS receiver’, for information on activating your receiver.
- Tap the the Start/Stop Editing button.
- Tap the Road layer to select it for editing.
The Command bar is automatically displayed.
- Tap the Polyline feature tool.
The Add GPS Vertex and Add GPS Vertices Continuously buttons are enabled.
- Tap the Add GPS Vertex button to capture a new vertex. Continue to do so until
you have reached the end of the extended road. Alternatively, use the Add GPS
Vertices Continuously button to capture vertices in streaming mode. Vertices are
captured according to the specified streaming vertices interval which is set in
the GPS Preferences dialog box.Tip:
Tip: Use snapping to snap the end of your new road to the end of the existing road. See section ‘Editing basics’, for information on snapping.
- Tap the Proceed tool on the Command bar when you are finished adding your road.
The feature dialog box opens so that you can immediately enter information about the new road.
- Fill in the form as follows: Feature Type = Road; Road Name =New; Road Type=
Lane, Class Code= Not Classified, and Road Seal = Gravel.
- Tap OK.
Your new road has been added and you are ready to move on to the next task.
